Answer:
57.72 in^2
Step-by-step explanation:
Question 1. Shapes are triangle, semi-circle, and rectangle.
Question 2.Find area of rectangle first. Then area of triangle and circle. Subtract area of triangle and circle. Then add the difference with the rectangles area.
Question 3.
Rectangle's area:48 in^2
Triangles area:8*4/2= 16 in^2
Circle Area: pi*r^2/2(since its a semi-circle)
3.14*2^2=3.14*4=12.56/2=6.28 in^2
Question 4.
16-6.28=9.72
9.72+48=57.72 in^2

The sum of three consecutive even numbers is 144. Find the highest even number.( Take the lowest even number as 4x-2)
[tex]\bold{\huge{\underline{ Solution }}}[/tex]
Given :-The sum of 3 consecutive even number is 144The lowest even number as 4x - 2 To Find :-We have to find the highest consecutive number. Let's Begin :-Here ,we have
The sum of three consecutive even numbers is 144[ Consecutive even numbers are the sequence of numbers that differ by 2 or that are divisible by 2 ]The lowest even number is 4x - 2Let the three consecutive number be
(4x - 2) , 4x , ( 4x + 2)
According to the question,
[tex]\sf{ (4x - 2) + 4x + ( 4x + 2) = 144}[/tex]
[tex]\sf{ 4x - 2 + 4x + 4x + 2 = 144}[/tex]
[tex]\sf{ 8x - 2 + 4x + 2 = 144}[/tex]
[tex]\sf{ 12x = 144}[/tex]
[tex]\sf{ x = }{\sf{\dfrac{ 144}{12}}}[/tex]
[tex]\sf{ x = }{\sf{\cancel{\dfrac{ 144}{12}}}}[/tex]
[tex]\sf{ x = 12 }[/tex]
Thus, The value of x is 12
Therefore,
The three consecutive even numbers are
[tex]\sf{ 4x - 2 = 48 - 2 = 46 }[/tex][tex]\sf{ 4x = 48 }[/tex][tex]\sf{ 4x + 2 = 48 + 2 = 50 }[/tex]Hence, The highest consecutive even number is 50 .

Answer:
y = 24
angle V = 67
as a 4 sided shape, the angles all have to add up to 360 degrees.
we already have the answers for R, 120, and B, 53. We have 187 degrees left to work with.
Based of the information the tics on the sides of the figure gives us, we know that angle P and R are the same! First (just for fun, this isn't needed) we'll find X.
(x+95) = 120
-95 -95
x = 25
We know 3/4 angles now, so by subtracting their sum from 360, we'll find angle V!
360 - 53 -120 - 120 = 67
Angle V is 67
Now to find y!
(2y+19)=67
-19 -19
2y = 48
/2 /2
y = 24

Step-by-step explanation:
boys to girls = 140:120 so we can simplify by 20 to get 7:6
boys to total = 140:(120+140) = 140:260 we can simplify again to get 7:13.
girls to total = 120:(120+140) = 120:260 we can also simplify to get 6:13

find all the zeros of the equation y=x^4+3x^3+x^2-12x-20
Answer:
x = 2, -2
explanation:
[tex]\sf y=x^4+3x^3+x^2-12x-20[/tex]
Find a factor for this equation:
-5 < x < 5
-------------
f(-3) = 25
f(-2) = 0
f(-1) = -9
f(0) = -20
f(1) = -27
f(2) = 0
f(3) = 115
Hence found that ( x -2) and ( x + 2) are the factor of the following equation.
Divide both by the following equation:
[tex]\sf \rightarrow \dfrac{x^4+3x^3+x^2-12x-20}{\left(x-2\right)\left(x+2\right)}[/tex]
[tex]\sf \rightarrow \dfrac{\left(x-2\right)\left(x+2\right)\left(x^2+3x+5\right)}{\left(x-2\right)\left(x+2\right)}[/tex]
[tex]\sf \rightarrow x^2+3x+5[/tex]
Using quadratic formula: [tex]\sf x = \frac{ -b \pm \sqrt{b^2 - 4ac}}{2a} \ \ when \ \ ax^2 + bx + c = 0[/tex]
[tex]\sf \hookrightarrow x_{1,\:2}=\dfrac{-3\pm \sqrt{3^2-4\cdot \:1\cdot \:5}}{2\cdot \:1}[/tex]
[tex]\hookrightarrow x=-\dfrac{3}{2}+i\dfrac{\sqrt{11}}{2},\:x=-\dfrac{3}{2}-i\dfrac{\sqrt{11}}{2}[/tex]
Thus the zero's of the function are:
x = 2, -2
Answer:
[tex]x=2, x=-2[/tex]; [tex]\frac{-3\pm i\sqrt{11}}{2} \in \mathbb{C}[/tex]
Step-by-step explanation:
Zeroes are found by setting the RHS = 0.
Since the quantity [tex]x^4+3x^3+x^2-12x-20[/tex] is a 4th degree polynomial there isn't a formula that gives us the solution, so we're stuck having to divide: to do so we make THE LIST: you list the divisors of the constant term without its sign (20: 1,2,4,5,10,20), the divisor of the lead coefficient (1), and you divide the first by the second in any possible way, adding a plus or minus:
[tex]\pm1, \pm2, \pm4, \pm5,\pm10,\pm20[/tex]. At this point you just have to check, replacing each one in the equation until you find two values that work (why two? You need to lower the degree of the polynomial by two, if you found only one you'd be stuck with a third degree equation which doesn't have an "easy" solving formula).
After some adding and multiplying you find that both 2 and -2 make the expression to zero. At this point you have two options
First is to divide the given expression by[tex](x-2)(x-2)=(x^2-4)[/tex] or, as I did in the image, notice that you will end up with a 2nd degree polynomial, whose coefficient you find by multiplying and confronting with the original equation.
Either way, you will end up with
[tex](x+2)(x-2)(x^2+3x+5)=0[/tex]
First two factors will give [tex]x=-2; x=2[/tex] respectively, while the third term has no real solutions (it still offers a pair of solutions in [tex]\mathbb{C}[/tex] which I'll add for the sake of completeness, but you're most likely required to look for real solutions only).

A student has an average score of 90 on four tests. If the student scored 88, 96 and 92 on the first three tests. What was the students score on the fourth tests
Answer:
84
Step-by-step explanation:
(92 + 96 + 88 + x) ÷ 4 = 90
92 + 96 + 88 + x/4 = 90
276 + x/4 = 90
(276 + x) × 4/4 = 90 × 4
276 + x = 360
x = 360 - 276
x = 84

1. In ∆MNO, what is the included side of <M and <O?
2. In ∆ABC, what is the included angle of sides AB and AC?
Answers:
Segment MOAngle A====================================================
Explanation:
The included side between two angles is simply the segment with the endpoints mentioned. So we involve endpoints M and O to form segment MO. This is the same as saying segment OM. The order doesn't matter.The angle between two sides involves the shared letter. For sides AB and AC, that shared common letter is A. Therefore, angle A is the included angle between the sides. We can refer to it as angle BAC or angle CAB, but angle A should suffice as a name assuming there aren't any other letters as part of the diagram.please help, this is due tomorrow
True or false. justify your answer.
if horse A is twice as far as horse B from the center of a merry-go-round, then horse A travels twice as fast as horse B
Answer:
TrueStep-by-step explanation:
Horse A travels twice the distance horse B travels.
It is because the distance, the circumference of circle, is the function of the radius. The circumference is directly proportional with the radius.
Since r₁ = 2r₂, the distance is:
C₁ = 2πr₁ = 4πr₂C₂ = 2πr₂The time of travel is same so the difference is reflected in the speed.
The horse A has twice the speed of horse B.
The prices of consumer goods do not always exactly follow the CPI. The following chart shows several consumer items, along with their respective prices in 1983 and today. Item Price in 1983 ($) Current Price ($) Shower curtain 8. 85 15. 66 Floor rug 71. 25 119. 75 T-shirt 13. 95 23. 99 Oscillating fan 22. 75 37. 50 Using the prices shown on this chart, which of the following is a reasonable estimate of the current CPI? a. 164 b. 170 c. 185 d. 199.
The reasonable estimate of the current customer price index is 195. The option B is the correct option.
Customer price indexCustomer price index is the price index which measures the weight average of price of basket of customers goods or services.
It can be given as,
[tex]\rm CPI_t=\dfrac{C_t}{C_0}\times 100[/tex]
Here [tex]\rm C_t[/tex] is the cost of market basket in current period and [tex]\rm C_0[/tex] is the cost of market basket in the base period.
Cost of market basket in current period is
[tex]\rm C_t=15.66+119.75+23.99+37.50\\\\C_t=196.9[/tex]
Cost of market basket in 1983 is,
[tex]\rm C_0=8.85+71.25+13.95+22.7\\\\C_0=116.8[/tex]
Substitute all the values in the formula
[tex]\rm CPI_t=\dfrac{C_t}{C_0}\times 100\\\\\rm CPI_t=\dfrac{196.9}{116.8}\times 100\\\\\rm CPI_t=1.685\times 100 \\\\ CPI_t=168.5\\\\\rm CPI_t= 170 \ \rm approx[/tex]
Thus the value of current CPI is 168.5 which is near about the 170.
Hence, the reasonable estimate of the current customer price index is 195. The option B is the correct option.

Answer:
Step-by-step explanation:
15(5+2) is the Answer
The greatest common factor to rewrite 75+30 as 15(5+2)
What is GCD?Greatest common divisor (GCD) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.
An expression is a combination of numbers, variables and operators.
The given expression is 75+30.
By using distributive law we can find this.
Let us find factors of 75 and 30.
The factors of 75 are 1, 3, 5, 15, 25, 75
The factors of 30 are 1, 3, 5, 9, 15, 45
Their GCF is 15.
To get 75, we will multiply 15 by 5.
To get 30, we will multiply 15 by 2.
By using distributive property
75+30 can be splitted to factors as
15(5+2)
Hence the greatest common factor to rewrite 75+30 as 15(5+2)
